to many image samples to trace for Light Cache- help me

[thradriel]

Hi there,

I have a problem between two versions of vray. I have a Laptop with Rhino 4 and vray 1.5.0202 as demo version.

When I render my scene there is this line in the progress window 'Tracing 250000 image samples for light cache in 8 passes.'

It works just fine.

My final output rendering must have the resolution of 3357x3357 , so nothing for the demo version. I went to my university to the computer pool.

They have rhino 4 with vray 1.05 (education license). I open my scene change the settings to the same like home.

Problem: 'Building light cache...' takes way too long. 3 hours and still there

I guess the problem is there: ' Tracing 2147483648 image samples for light cache in 8 passes.'

Question: How can i lower those sampels? Why does it change that much although the settings and scene are the same?

Thanks for any help or suggestions...

@moderator can be deleted... clicked on a script button with primary and secondary light cache and some sort of progressive mode
